Quercus spp.; white oak
[Fagaceae]
Wisconsin oaks are all deciduous trees,
but many of the world's many oak species are evergreen, and some change
character depending on site.
Wisconsin members of the WHITE OAK GROUP of species have leaves with
rounded lobes. Their acorns
mature in one year, are not bitter, and their shells are hairless
inside. Examples:
Q. alba (white oak) is
found in well-drained woods;
Q. bicolor (swamp white oak) is found in swamps; and
Q.macrocarpa (bur oak)
does well on drier sites, and is most abundant in the southwestern part
of the state.
